DUMPlNG-CAR.'

SPECIFICATION forming part of Letters Patent No. 249,928, dated November 22, 1881.

Application filed October 3, 1681. (ModeL) To all whom it may concern:

Be it known that I, JosnPH S. HALSEY, of Lebanon, in the county of Warren and State of Ohio, have invented a new and Improved Dumping-Oar, of which the followingisa specification.

The object of this invention is to provide a central-unloading car,-in contradistinction to a side or end unloading car, specially designed for dumping earth, 850., on railroads, &c.

The invention consists of a car having a platform constructed in longitudinal sections, that are pivoted at their ends within inclined slots madein the car-sills in such a mannerthat when the platforms are elevated at their outer edges the weight of the load will cause their pivots to slide down the incline of the slots and depress the platforms at their inner edges, whereby the load will be .centrally dumped through an opening along the entire length of the platform.

The invention further consists of novel devices and mechanism for supporting and for tilting the platforms, and also in a novel mode of constructing the central section of the platform, all of which will be hereinafter described.

. In the accompanying drawings, Figure 1 is a transverse sectional elevation of my improved car-platform. Fig. 2 is a longitudinal sectional elevation of the same on line a as, Fig. 1. Fig. 3 is a perspective view of a modification of the same. Fig. 4 is a cross-section of the car-platform shown in Fig. 3 in position for discharging a load. Fig. 5 is a cross-section of another modification of the car-platform.

Similar letters of reference indicate corresponding parts in all the figures.

In the drawings, A A represent the end sills of the car, held together by two side stringers,BB, and two stringers, KK, that are placed a short distance inward from the stringers B, and afford central support to the tilting platform-sections E E. These sills and stringers A B K are designed to be securely fastened together and to be iron-clad wherever necessary to protect them from wear.

Along the central line of the car is a central platform-section, consisting of a stringer, 1 having axles 8 formed on each end, carrying a platform, 0, that extends slightly on each side of the said stringer P, and overlaps on the platform-stringers F, to be supported thereby and prevented from tilting when the platformsections E E are down in place, with the axles d d in the flat parts 0 of the sockets b, said stringers P being made of strong timber, to resist the weight of a load of gravel.

Through the sills A A, on either side of the stringer P, diagonal slots or sockets I) Z) are formed, sloping outward and downward, the upper ends of said sockets I) being, however, horizontal or flat'for a short distance, as shown at c, for reasons hereinafter set forth.

E E represent the movable or tilting platformsections, strengthened on their under sides at their inner edges by longitudinal stringers F F, preferably of square cross-section, as shown,

which stringers F F have fashioned on their ends or connected thereto short axles d d, that rest in the flat parts c act the sockets b b. Near their outer edges these platform-sections E are strengthened on their under sides with stringers G G, whose outer faces are preferably beveled off downward to conform with and rest upon the inner sloping faces of the fixed stringers B of the car-frame, so that the outer edges of the said sections E E shall be thereby supported when they are down, as shown in Figs. 1, 3, and 5, and at the same time the axles d d, resting in the flat or horizontal portions 0 of the sockets b I), support the inner edges of the sections E E, so that said sections E E shall not yield beneath any load that may be placed on them, but be thereby, retained in a horizontal position. Said platform-sections E E are further secured down in place by means of eyebolts ff, that are fixed in the stringers B B, and have their heads passed up through corresponding openings in the edges of the sections E E, and by pins 9 g driven through said eyebolt-heads, as shown.

Centrally upon the sills A A are firmly fixed iron uprightposts or stanchionsH H, the one at the rear end, H, of the car having two perforations in its cap for the engagement of the rings h h of the platform-hoistin g device, while in the double cap of the forward stanchion, H, are pivoted on upright pins it, two sheaves, ll, whose functions will be hereinafter set forth.

Arope or chain,I, is made fast to each ring h, and, passing down and along each side, are reeved through pulley-blocks m, that are secured on the platform-sections E E, near the edges thereof, and are then passed upward about the sheaves l land led forward with the design of being attached to the engine or other device, (not shown,) by means of which said ropes or chains I are drawn taut and the platform-sections E E thereby tilted inward, as shown in Figs. 1 and 4. These stanchions H H are designed to be of suificient height to make the tilting of the platform E E a comparatively easy matter without two much strain upon the ropes or chains I. When the car is loaded and power is applied to these ropes or chains I, the pinsg g being removed, the outer edges of the platforms E begin to rise, and the axles d d are thereby moved outward from the horizontal or flat portion 0 of the socket b, and then fall by the weight of said platforms and the load upon them to the bottoms of said sockets I), thus facilitating the tilting of said platforms E E, and at the same time holding the inner edges thereof so far from the central platform,(), that ample space is given for the discharge of the load between said platform 0 and the inner edges of the sections E E. When the chains or ropes I are slackened the sections E E fall outward by their own gravity, and are forced into a closed position by the contact of the outer faces of the stringers G against the sloping inner faces of the stringers B.

In front of the car the ropes I should be united in a single rope to connect with the engine, whereby the said ropes I should be free to adjust themselves,and their tension be thereby equalized, so that both of the platforms E E should be elevated and lowered simultaneously.

If it is desired to unload a load of gravel at once beneath a car, the sections E E are tilted, as previously described, the inner edge of each dropping downward and outward, leaving the central section, 0, in position,unless the weight upon one side of it is much greater than that upon the other, in which case it will turn upon its axles s and unload itself. If the weight be evenly distributed on the section 0, a little work with shovels will disturb the equilibrium, and said section 0 will then rotate and discharge its load; but if only a small part of the load is to be let off, but one side section E will be elevated first, and the weight of the gravel on the other side of the car will hold the mid- .dle section,O, in position. When partially uncentral peak, a, uppermost, and the faces sloping outward and downward, that the load may easily discharge therefrom. In this modified car the stringers K are dispensed with, the stringers O 0 being substituted for them, in forming the car-frame, in combination with the stringers B and sills A.

In the above modification the platform-sections E are operated as in the former case already described.

L represents the axles, and M the wheels, of the car.

In Fig. 5 is shown another modification of the car, wherein there is an absence of a central platform, and the tilting sections E E meet at the lotlgitudi nal center ot'the car and receive longitudinal support from stringers K K, that are framed into the sills A A. The method of operating these platform-sections E E is the same as that described in the former cases.

The forms of car shown in Figs. 1, 2, and 5 may be used to most advantage on narrowgage roads, especially that form shown in Fig. 5, where the width of the cars is not so great as those on the standard-gage roads, or where a heavy graveling is not needed, and where expedition in unloading is desirable.

The form shown in Figs. 3 and 4 may well be used on the standard-gage road.

In order to secure the fall of gravel over the trucks of the car, and also to protect the cartrucks, a wide and strong hollowed iron chute should be fastened to the inner permanent sills, extending far enough down and outward over the two sides to receive within its deep hollow slant the fall of the gravel. A smaller chute of similar construction may, if desirable, cover each axle.

The standards H may be adjustable, so that they may be transferred from one car to another.

These improved cars can be used for hauling wood, timber, &c., as well as for gravel. By the use of this improved car gravel, 850., can be dumped on the center of the road bed instead of at the sides thereof, as by the ordinary car, thereby saving much time and labor in spreading it; and the whole or a part of a load can be dumped at a time, thus facilitating the repairing and regrading of railroad-tracks.

The use ofmy invention will necessitate making the end sills of dumping-cars one or two inch es deeper than such sills are usually made, in order that the inclined slots therein may be of suflicient length to afford a large dischargeopening for the contents of the car.

I do not confine myself to the precise construction hereinbefore described, as it may be modified in some particulars without departing from my invention-as, for instance, the strain upon the ropes or chains 1 and standards H H may be lessened by making the pivoted platforms quite narrow; and, to prevent the gravel from falling too far outward, inclined wood or iron chutes may be fastened along the permanent longitudinal sills to guide the descending gravel and insure its fall between the rails; and, instead of the fixed central platform-section, D, being constructed with central peak, a, and inclined or sloping faces, as shown in Figs. 3 and 4, the upper face of said section D may be of rounded form to insure the automatic discharge of the central portion of the load therefrom on the tilting of the pivoted side platforms; and, instead ofbevcling the car-stringers B G or their respective inner or outer faces, beveled or angular blocks may be secured to corresponding stringers of rectangular cross-section and the seating of the axles or pivots d in the slots 0 be as well effected, meanwhile securing a saving in labor and material in the construction of the car.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a dumping-car, the platform E, constructed substantially as herein shown and 'de-- scribed, with sliding axles, as set forth.

2. A dumping-car constructed with fixed longitudinal central platform-section, having inclined or rounded upper face, and with adjacent pivoted side platforms, substantially as herein shown and described, whereby the central portion of the load will be automatically dicharged upon the tilting ofthe side platforms,
